Question 13

Normal values for

Na+, K+, Cl-, HCO3-, Anion Gap

Answer 13

Na+ (137-147)
K+ (3.5-5)
Cl- (98-105)
HCO3- (22-28)
Anion Gap (8-16)

Question 14

Calculate Mean Arterial Pressure (MAP)

Answer 14

MAP= SP + DP (2) / 3

Question 15

Calculate Systemic Vascular Resistance (SVR)

Answer 15

SVR = Mean arterial pressure (MAP) - Right atrial pressure or Central venous pressure (RAP) (CVP) divided by the Cardiac Output (CO) x 80

SVR = MAP-RAP/CO x80

Question 16

Calculate Pulmonary Vascular Resistance (PVR)

Answer 16

PVR= Mean pulmonary artery pressure (MPAP) - pulmonary capillary wedge pressure (PCWP) divided by Cardiac output (CO) x 80

PVR= MPAP-PCWP/CO x 80

Question 17

Calculate Qt (cardiac output)

Answer 17

Qt= Vo2 x100/Ca02-Cv02

Answer 18

Decreased HB, Decreased arterial BP
C.I. less than 2.5
slightly low PAP and PCWP
slightly high C(a-v)02
low Pv02 and Sv02

Question 19

Cardiogenic shock

Answer 19

Decreased CO, BP
C.I. <2.5
Increased PAP, PCWP and C(a-v)02
Decreased Pv02 and Sv02

Question 20

Left ventricular failure

Answer 20

Decreased BP, CO
C.I. <2.5
High PAP and PCWP(sometimes over 20), and normal to inc. C(a-v)02
Decreased Pv02 and Sv02

Question 21

Fluid overload

Answer 21

Increase or normal BP, CO
C.I. above 4
Increased PAP and PCWP
Normal or increased Pv02 and Sv02
Normal of decreased C(a-v)02

Question 22
